Continuum does not execute builds when last BUILDRESULT.END_TIME=0
------------------------------------------------------------------

                 Key: CONTINUUM-1871
                 URL: http://jira.codehaus.org/browse/CONTINUUM-1871
             Project: Continuum
          Issue Type: Bug
    Affects Versions: 1.2
         Environment: RHEL 5, Continuum 1.2 (SVN 691325), Java 1.6.0_03, MySQL 5.0.45, Maven
2.0.9
            Reporter: Peter Janes
         Attachments: thread-dump.txt

After adding a set of projects to a Continuum 1.2 instance, the server stopped performing
any builds on any projects.  CPU usage shoots up to 100%, projects are queued up and are apparently
started, but no build processes are invoked.  Even the simplest pom-only job times out.

Looking at the database I noticed that the last entry for the top-queued project in the BUILDRESULT
table had an END_TIME of 0.  When I changed that field to a current time and restarted the
server Continuum started to perform builds again.

I was able to duplicate the problem by setting the END_TIME of the last BUILDRESULT of a project
to 0, starting the server, and waiting for that project to be queued.  The problem was resolved
again when I reset END_TIME to its original value.

I've attached a thread dump as suggested on users@continuum.  It seems to show that Continuum
is in the SCM module's ChangeSet.toString(), which doesn't seem right, but perhaps it will
help point to the root cause.
